Green River
The Green River, a tributary of the Colorado River, originates in Wyoming, where it flows 291 miles (468 km) before entering the state of Utah. It runs for 42 miles (68 km) in Colorado, and once journeying into Utah, runs another 397 miles (639 km). The confluence of the Green and Colorado Rivers is in Canyonlands National Park.[2]
